Researcher: What Global Warming?

It's been a rough winter in Wisconsin with record breaking snow falls and low temperatures. The beginning of spring has continued to see snow flurries. Dennis Avery, Senior Fellow at the Hudson Institute, believes temperatures are being affected by natural cycles with the sun. He believes there is a strong correlation between how long sunspot cycles last and how cold the earth gets. He says the current sun spot cycle has lasted 12 years, rather than a more common cycle of 11 years, and hasn't ended yet.

He believes the "greenhouse gas" Co2 is not a significant factor in raising temperatures. He points to a timeline from 1976 into the 1990's, CO2 levels went up along with a rise in temperatures. However he says, "It looks now like that was a coincidence because since 98 the Co2 has continued to soar, while the temperatures have declined."
